In the Sales Journal, if I post a line with Account type is “Customer” and set a bill-to number in the customer card for it. Then system will pop up a notification and change the bill-to value to customer number automatically. Also, bill-to field in the Sales Journal is unable to modify.

However, Bill-to is working fine in the sales invoice.

When posting needs to go to bill-to customer, if you do the same on a sales invoice it works correctly.
